    • A Compact Representation for Fluorescent Spectral Data 

      Hua, Qingqin; Fichet, Alban; Wilkie, Alexander (The Eurographics Association, 2021)
      We propose a technique to efficiently importance sample and store fluorescent spectral data. Fluorescence behaviour is properly represented as a re-radiation matrix: for a given input wavelength, this matrix indicates how ...

    • Fast Analytic Soft Shadows from Area Lights 

      Kt, Aakash; Sakurikar, Parikshit; Narayanan, P. J. (The Eurographics Association, 2021)
      In this paper, we present the first method to analytically compute shading and soft shadows for physically based BRDFs from arbitrary area lights.We observe that for a given shading point, shadowed radiance can be computed ...

    • Firefly Removal in Monte Carlo Rendering with Adaptive Median of meaNs 

      Buisine, Jérôme; Delepoulle, Samuel; Renaud, Christophe (The Eurographics Association, 2021)
      Estimating the rendering equation using Monte Carlo methods produces photorealistic images by evaluating a large number of samples of the rendering equation per pixel. The final value for each pixel is then calculated as ...

    • A Low-Dimensional Perceptual Space for Intuitive BRDF Editing 

      Shi, Weiqi; Wang, Zeyu; Soler, Cyril; Rushmeier, Holly (The Eurographics Association, 2021)
      Understanding and characterizing material appearance based on human perception is challenging because of the highdimensionality and nonlinearity of reflectance data. We refer to the process of identifying specific ...

    • MatMorpher: A Morphing Operator for SVBRDFs 

      Gauthier, Alban; Thiery, Jean-Marc; Boubekeur, Tamy (The Eurographics Association, 2021)
      We present a novel morphing operator for spatially-varying bidirectional reflectance distribution functions. Our operator takes as input digital materials modeled using a set of 2D texture maps which control the typical ...

    • Modeling Surround-aware Contrast Sensitivity 

      Yi, Shinyoung; Jeon, Daniel S.; Serrano, Ana; Jeong, Se-Yoon; Kim, Hui-Yong; Gutierrez, Diego; Kim, Min H. (The Eurographics Association, 2021)
      Despite advances in display technology, many existing applications rely on psychophysical datasets of human perception gathered using older, sometimes outdated displays. As a result, there exists the underlying assumption ...

    • Moment-based Constrained Spectral Uplifting 

      Tódová, Lucia; Wilkie, Alexander; Fascione, Luca (The Eurographics Association, 2021)
      Spectral rendering is increasingly used in appearance-critical rendering workflows due to its ability to predict colour values under varying illuminants. However, directly modelling assets via input of spectral data is a ...

    • NeLF: Neural Light-transport Field for Portrait View Synthesis and Relighting 

      Sun, Tiancheng; Lin, Kai-En; Bi, Sai; Xu, Zexiang; Ramamoorthi, Ravi (The Eurographics Association, 2021)
      Human portraits exhibit various appearances when observed from different views under different lighting conditions. We can easily imagine how the face will look like in another setup, but computer algorithms still fail on ...

    • Single-image Full-body Human Relighting 

      Lagunas, Manuel; Sun, Xin; Yang, Jimei; Villegas, Ruben; Zhang, Jianming; Shu, Zhixin; Masia, Belen; Gutierrez, Diego (The Eurographics Association, 2021)
      We present a single-image data-driven method to automatically relight images with full-body humans in them. Our framework is based on a realistic scene decomposition leveraging precomputed radiance transfer (PRT) and ...
